One Piece: Protecting Ace, Starting from Mount Colubo

I don't have much time right now, so I haven't written a lot of things or researched them in detail. I plan to wrap things up quickly and bring the story to its conclusion.

[Transmigration + Pirate King + System + Ace]

I stood at the beginning of the story, already seeing his inevitable death.

The System ordered me to watch from the sidelines, but I couldn't stop myself from getting close and staying by his side through his hardest years.

I watched him grow from a lone-wolf boy into the dazzling captain of the Whitebeard Pirates.
